PACKAGING BOX HAVING SAFETY LOCK FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/067903
Kind Code:
A1
Abstract:
A packaging box having a safety lock function. A plurality of outer engagement protrusions (8) are provided on the outer bottom of a locking cover body (7) to form an upper annular engagement structure, and an engagement slot is formed between every two adjacent outer engagement protrusions (8); a plurality of inner engagement protrusions (6) are provided on the inner bottom of an unlocking cover body (3) to form a lower annular engagement structure, and an engagement slot is formed between every two adjacent inner engagement protrusions (6). When the upper annular engagement structure mates with the lower annular engagement structure, the locking cover body (7) is stressed to achieve unlocking of the box body and the cover body; when the upper annular engagement structure is separated from the lower annular engagement structure, the locking cover body (7) is not stressed, so that the box body and the cover body are in a locked state. The upper annular engagement structure and the lower annular engagement structure are provided on the respective bottoms of the locking cover body (7) and the unlocking cover body (3), such that unlocking requires the unlocking cover body (3) to move by a larger stroke, to further ensure that a child cannot open the packaging box by misoperation.
